We had the Duffy finished for tuna fishing and so we could spend the weekend on it. Atlantic Boats sent us scale plans of the boat and we spent a year getting things where we wanted and so they would fit in the boat.
What's in the boat starting from the stern: two 110v underwater lights tilled down 15 degrees, tuna door with ramp, the ramp cover has floation so it will float, 11'-4"x2'-5"x2'-7"deep fish hole (2375lbs ice and fish) with pen boards, two 275gal. fuel tanks, outside shower and steering station, cockpit is 15' long. In the house and down below: 6kw genny, 800hp Cat 3406E, tackle cabinet with 4 8D batteries in bottom three draws and the white plastic butcher cutting board on top, table, L shaped bench seat, main steering station with electronics, inshore rod storage overhead, galley down, head, two bunks with offshore rod storage overhead.
I agree with Hunta the boat likes any sea but if I had to pick the sea it likes the least it is a dead on head sea. A few degree off dead on is no problem. Yes it is a big 38'. "Absolutley dwarfs the 35." That is an under statement. If you put the 35 and 38 next to each other it looks like you could put the 35 in my cockpit.
The boat cruises at 23kt burning 28gal/hr and we can get down to 3kt with the trolling valve. At 600rpm the boat does 6kt and at 550rpm with the slow engine switch on it does 5kts. We are docked on the south end of the Shinnecock Canal. The tides of Peconic Bay and Shinnecock Bay are opposite. There are locks in the canal that only let the current flow south. Docking at 5kt backing with a 3-5kt current is fun.
That is something about the boat I had a ton of pictures of the build and boat. Ask any questions you have and any pictures you want to see and I'll post them.
